The location of the image layer with respect to how a patient is positioned in a rotational panoramic machine is very critical. At present, no simple method exists for routine testing of panoramic machines to verify that the image layer is where the manufacturer intended it to be. The purpose of this experiment was to locate the central plane of the image layer with respect to a reference point on various machines currently on the market. The data obtained from this study can be used for further evaluations of the consistency in the location of the image layer, first with the existing device and later with a test device that would be adaptable to these machines and serve as a quality-control device in assuring that the machines are functioning properly.
图像层相对于患者在旋转全景机中的定位方式非常关键。目前，不存在用于全景机常规测试的简单方法来验证图像层是否处于制造商预期的位置。本实验的目的是相对于市场上现有各种机器上的参考点来确定图像层的中心平面。从本研究中获得的数据可用于进一步评估图像层位置的一致性，首先使用现有设备，之后使用适用于这些机器并作为质量控制设备以确保机器正常运行的测试设备。
